What is LNG?As an emerging industry in B.C., LNG offers us a rare opportunity
Liquefied natural gas (LNG) is natural gas chilled to about -162° Celsius, the point at which natural gas condenses to liquid. The cooling process takes place in a LNG facility, similar to a large refrigerator.
LNG is non-explosive, non-toxic, non-corrosive and does not mix with water or soil. In case of a release it becomes a natural gas again and mixes into the atmosphere, causing no environmental or other impacts.
In a liquefied state, LNG takes up about 1/600th of the space of natural gas in its vapour state, making it more efficient to transport in specially designed carriers to overseas markets.
Natural gas is a clean-burning fuel that produces fewer greenhouse gas emissions than other hydrocarbons.
LNG is the same natural gas used throughout Canada to heat our homes, schools and businesses; cook our food; and, increasingly, fuel trucks, buses and ships.
Customers who buy LNG will use it for these same purposes. They will also use it to displace coal when generating electricity which leads to lower green house gas emissions.
LNG has been transported safely worldwide for more than 50 years. Over that period, more than 71,000 loaded LNG voyages covering about 151 million miles have occurred without any significant incidents at sea or in port.
LNG carriers are specially designed and used only for LNG transport. They are double-hulled and have sophisticated leak detection technology, safety monitoring systems and advanced navigation equipment to ensure the LNG is transported safely.
As a new industry to B.C., producers have the advantage of being able to build and operate the most modern and safest LNG facilities in the world.
LNG facilities have multiple layers of protection, including:
If LNG escapes into the atmosphere, it simply converts back to natural gas and mixes safely with the air.
Producing Natural Gas
LNG facilities in B.C. will export natural gas extracted primarily from the northeastern region of our province where it has been safely produced for generations.
Most of the natural gas will be extracted using hydraulic fracturing, a regulated, safe and proven technology in use since the 1960s. This process involves injecting a mix of water, sand and small amounts of additives down a cement-cased well and out through holes in a steel liner to crack the shale rock and encourage gas to flow.
In B.C. all hydraulic fracturing occurs at a depth many kilometers far below groundwater aquifers, so no contamination can happen. Wells are lined and cemented with steel casings to prevent the natural gas or hydraulic fracturing fluid from coming in contact with the water.

LNG Projects in British Columbia
LNG Projects in British Columbia
Alliance members bring decades of experience, insight and best environmental practices to British Columbia. Our members will develop an LNG industry that British Columbians can be proud of: safe and environmentally responsible.
In practising responsible environmental stewardship, all of our members will identify potential environmental impacts and design ways to eliminate or mitigate adverse impacts to the air, land and water.
All LNG projects must undergo independent environmental assessment processes under the Canada and British Columbia Environmental Assessment Acts. Science-based and comprehensive, environmental assessments provide opportunities for public participation in the review process.
